Not sure of the skill level Erin but there's always,
Syrinx, Debussy
Danse De La Chevre, Honneger
Also Ibert wrote a Solo called Piece for Flute Solo which is less thematic and has something to work on
Not as "Faiery-like" because it's SW Indian style but it's out there and not too difficult is the Kokopelli By Hoover.
Of course there's always those Telemann Fantasias
The Bach a minor Solo Partita and Sarabande.
Or something from the C.P.E. Bach a Minor Sonata would work.
You could play the much overworked theme from the Pachelbel Canon but it's not technically a Canon when played as a solo piece.
